goback & goforward multiple times

[Elan Dekel]

I'm creating a web browser using the internet control with a "back" and
"forward" dropdown menu, like Explorer 4.0. The user should be able to
select a page that is a certain number of places forwards or backwards in
the history. However the internet control only provides Goback and
GoForward, which only works one step at a time. How can I instantly jump
more than one place forwards or backwards??
I tried looping through Goback and Goforward, as follows:

for i = 1 to num
webbrowser.goback
next i

The problem is that this loses the history of all the pages in between the
current page and the page we are jumping to.
I even tried:

for i = 1 to num
webbrowser.goback
doevents
next i

This keeps the history intact, but all the pages appear on the browser
one-by-one!

Any ideas?

Thanks,

Elan

How about using two Stacks, one for Back, and one for Forward?
You could store the history in the Stack, and when the user selects, say the
4th item in Back,
you just pop 4 times from the Back Stack(and push into Forward Stack).

Now you have the URL you want to go to, and can call Navigate.

You should use the interface:
IOmHistory

if you back num step, you only need call like this:
COleVariant var = (short)num;
back(&var);

But I don't know how to find history's content, thanks.

Thanks.
But how to record the user operation?

I'm not sure what you mean by that. You can create Back/Forward buttons with
Dropdowns, just like in IE4.
You must be able to identify how far Back or Forward in history the user
wants to go.

Admittedly, calling Navigate again is not identical to going Back, as in
IE4.
Any other suggestions will be appreciated.

Exactly, this is the problem! It shows up especially in frames. If you do a
navigate, then it replaces the entire frameset, while a back goes to the
previous page you viewed in the frameset. This is why it is important to me
to use back and forward.

Any other ideas?

Think I've found a solution.
Try:

frmWorkSpace.WebBrowser.Document.parentWindow.history.go(-num)

Good luck,

Elan

Does anyone know how to do this in J++, the getDocument method returns an
Object. This probably needs casting to something but what ?
